#3076 Endometrial Small Cell Neuroendocrine Carcinoma: Case Report and Literature Review

Introduction: Endometrial small-cell neuroendocrine carcinoma (ESCNEC) is extremely rare. It is characterized by early regional and systemic spread leading to rapid development of lymph nodes, pelvic and extrapelvic metastasis and compromising the outcome.

#3073 The Role of Rb as a Prognostic Factor in Grade 3 Poorly Differentiated Neuroendocrine Carcinoma (G3NEC) Treated by First Line Platinum-Etoposide Combination, a Retrospective Study

Introduction: G3NEC are heterogeneous and aggressive diseases which can arise in different organs. Platinum-etoposide combination is used as first line treatment whatever the primary. Rb has been suggested to be a predictive/prognostic factor.

#3072 Rb and p53 Status Determination by Immunochemistry Is Complementary in Routine Practice to Genetic Testing of Neuroendocrine Neoplasms

Introduction: Rb and p53 status may help distinguishing well from poorly differentiated neuroendocrine neoplasms (NEN) and may predict response to chemotherapy. Studies correlating Rb/p53 genetic and immunohistochemistry were performed on high-quality frozen samples with high throughput techniques efficient for copy number determination. This situation differs from routine practice in which small deletions may be hard to detect on formalin-fixed paraffin-embedded (FFPE) samples with a gene panel approach.

#3031 Primitive Peripheral Neuroectodermal Tumor: Case Report

Introduction: Primitive neuroectodermal tumors belong to the family of Ewing sarcomatous tumors, all derived from the same stem cell. The cells of the neural crest are believed to be at the origin of these tumors. The predilection sites of these sarcomas are para-vertebral region, chest wall and the distal ends. The positive diagnosis of primary neuroectodermal tumors requires the contribution of histopathology, immunohistochemistry and cytogenetics.
